Something I've just realised going into the office is how much more unproductive I make everyone else.
If I'm not working at home, everyone else is free to keep working. But if I'm not working in the office I'm going to drag everyone in my team down to my level.
I am at the opposite end. When I'm at the office, I put on noise cancelling headphones and don't talk to anyone unless it's necessary. It's not that I don't like them, it's that I just want to get my shit done and not have to deal with their shit.
